```
io.github.libtmux.Window.Window.applyLayout(layout: String) -> void
```

Restores an exact arrangement previously read from {@link #layout()}.

<p>The string is checked here rather than by tmux, because tmux 3.3a does not survive being
handed one it cannot parse: it ends the server and every session on the socket. Every other
supported release answers {@code invalid layout}. Since a layout string carries tmux's own
checksum, a wrong one is detectable without asking.

## Raises

- `IllegalArgumentException` — if the string is not a layout tmux wrote
